TrueNAS Scale and Docker Platform Issues

2 points by vanillax ↗ HN
I spent the weekend setting TrueNas Scale excited for the opportunity for native docker support and hardware passthrough, only to find the ability to use docker extremely limited. This post below, which is not authored by me, sum up the issues pretty well.

To make matters worse, you cant use standard helm charts. https://github.com/k8s-at-home/charts/issues/1093

I’ve been using scale since the alpha versions are am pretty happy with it tbh. Not a fan of what they are doing with the ui to create apps, but the underlying k3s is pretty much bog standard and you can just ignore the ui and do whatever you want using a terminal.

For example to install anything from the chart repo you linked:

> export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

> helm repo add k8s-at-home https://k8s-at-home.com/charts/

> helm search repo k8s-at-home

> helm install k8s-at-home/aria2 --generate-name

Hey thanks for replying!

When you go the command route as you stated here. Does the UI show k8-at-home as a catalog?

If I install a "app" from k8-at-home using the helm install, does it show up in the UI of TrueNas as a app? Or is everything done via terminal hidden from UI?

It does not show up in the UI. Everything done via terminal that doesn't have the magic/expected labels/annotations that truenas expect will not show up in the ui.
